Abstract
A battery pack charger configured to heat a power tool battery pack, the battery pack charger comprising a housing, an adapter portion integrated with the housing of the battery pack charger, the adapter portion configured to mechanically and electrically connect to the power tool battery pack, and an inductive heater including a coil portion, the coil portion including a coil housing and one or more inductive coil windings, the inductive heater configured to generate an electromagnetic field to heat the power tool battery pack.
Claims20
A battery pack charger configured to heat a power tool battery pack, the battery pack charger comprising:
- a housing;
- an adapter portion including a battery pack interface;
- and
- an inductive heater including a coil portion configured to encompass the power tool battery pack, the coil portion including a coil housing and an inductive coil winding, the inductive heater configured to generate an electromagnetic field to heat the power tool battery pack.
A battery pack enclosure, the battery pack enclosure comprising:
- a lower housing portion;
- an upper housing portion pivotably connected to a lower housing portion;
- an adapter portion including a battery pack interface;
- and
- an inductive heater including a coil portion, the coil portion including a coil housing and an inductive coil winding, the inductive heater configured to generate an electromagnetic field to heat a battery pack.
A battery pack enclosure, the battery pack enclosure comprising:
- a lower housing portion;
- an upper housing portion pivotably connected to the lower housing portion;
- a first adapter portion including a first battery pack interface;
- a second adapter portion including a second battery pack interface;
- a first inductive heater configured to generate an electromagnetic field to heat a first battery pack;
- a second inductive heater configured to generate an electromagnetic field to heat a second battery pack;
- and
- an ambient temperature sensor configured to receive a first temperature signal associated with the first battery pack and a second temperature signal associated with the second battery pack.
